Autobot hiearchy

So I was thinking about the leadership roles that each top autobot is supposed to play. After prime it seems to be ironhide, followed by jazz and thats about it.
I have watched all the toons and cant for the life of me figure out why people think prowl is secondish in command. Im sure it comes from somewhere but it escapes me.
Was it mentioned in his tech specs or in the comics perhaps?
Personally I love prowl. He is top five in my faves for sure but I cannot find a single scene where he assumes command of the autobots in the absence of optimus.
Can anyone shed a bit of light on this for me?
Thanks guys n gals!
